We stayed at the apartement for 2 days.
2 adults and 2 children. Our 3 year old slept in the small bedroom and we slept with our 10 month old in the masterbedroom.
The place is really nice. Its not huge, but its very well distributed, and has everything you need.
The apartement is on the top floor of the building (37.) and has a super nice view of Bangkok. We also really enjoyed the swimmingpool. Clean and refreshing.
Vit is such a nice guy, and he has thought of every little detail. Map of the area both in thai and english, water, fresh fruit in the fridge, airport pickup and drop off!!
We didnt go to the city center, since we have been many times, and we where just here to relax between 2 flights, so didnt have the need to go sightseeing. So I dont know how the place is located if you have to go downtown, but for us the area was great. Theres a huge shopping mall close by, and there was also lots of little street food places right next to. And also the usual 7-ellevens and familymart. So you have everything you need.
All in all a very good stay and good value. We have already booked the place again for when we come back to Bangkok ;-)
